To all wtom'z't may concern:

Be it vknown that I, STANLEY G. MILLER, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented a certain newA and useful Improvement in Grass Carpets, of which the following is a specification;

- rIhis invention relates to. woven carpets, and has for its object to improve the fabric of such carpets and to provide.structural l Y in place and prevent the separation of the ieans for producing tone effect.

The invention consists in thecombination and arrangement of parts described in the specification, shown in the accompanying drawings, and more particularly set forth in the appended claims.

In the drawing, Figure'l is a plan View of a piece of carpet embodying the present invention; Fig. 2 showsa small portion of the carpet considerably enlarged; and Fig. 3 shows a portion of one of the woof strands with the wrapping therefor.

In the manufacture of carpets, and particularly of grass carpets, it is a common practice to form the fabric by a warp composed of one kind of material anda woof of a different material. In grass carpets it" is usual to use strands of various grasses for the woof. It has heretofore been customary to produce a general tone effect by dyeing the grass composing the woof strands, and to lvary the design by the arrangement and coloring of the warp. t-he present invention a novel means is provided for producing the general tone effect in the carpet without the necessity of dyeing the grass which may be left in its natural color. The same means which is used for producing the tone effect also materially improves the carpet texture.

Referring to the drawing. the numeral l designates the strands which compose the woof of a carpet. These strands are made up of a bundle of fibers 2.' In the preferred embodiment of this invention,l the fibers 2 are of grass and are laid side by side with-l out twisting, so that they are substantially parallel with one another throughout the length of the woof strands. The fibers are held together in a cylindrical strand as shown in Fig. 3, by a wrapping 3 preferable of heavy cotton thread which is wound spirallyy .around the strand throughout its entire length. I prefer to use a double wrap- Speccation of Letters Patent.

more efficient in holding the fibers of the 1 strand in position than a single wrapping would' be, 'even though the lturns ofthe single wrapping were made close together, for the reason that thev two wrappings in crossing one another tend to hold each other Y fibers in the strand'. y Y

- 'IheV numeral 4 designates the strands of thel warp, these strands being interwoven with` the woof strands inthe usual manner. The arrangement and color ofthe warp strands may be varied in l'any of the usual ways to produce the figure effects of the carpet.4 This is .accomplished by various weaves of the'warp and woof as well as by the various colored threads used for the warp. i

The 4woof is preferably composedV of un`` dyed grass and the wrappings 3 of the woof are preferably all of the same color in a given p'-iece^ of "'carpet. The wrapping threads 3 are usually considerably smaller in size than the strands of the warp and individual threads .are comparatively inconspicuous. Because of their position, however, around the strands ofthe woof they may be used for producing any tone desired simplyby using different colors for these wrapping threads. When a carpet is viewed from a short distance, as it is when lying upon a floor, the individual wrapping threads `are practically lost sight of but the whole carpet is given a tone depending upon the color of these` threads. If green threads are used, a greenish tone will be produced, or if brown or blue or yellow threads are used, the tone of the carpet will vary accordingly. If very dark threads, such as black, are used, a Vpeculiar mottled Y effect is secured,l due to the criss-crossing of which the carpet is made. It is of course apparent that the strands of the woof may be twisted, if desired, to any extent found advantageous.

Having thus described my invention, what I claim as new and desire to secure byvLetters Patent of the United States is l. In a. grass carpet, the combination with a fabric having woof strands and warp strands, the woof strands being composed of fibers of undyed grass, of means for imparting a tone effect to said fabric comprising a spiral wrapping for said Woof strands of a color di'erent from said warp strands.

2. In combination with a fabric comprising warp strands and Woof strands, the

woof strands being composed of fibers of undyed grass, of means for holding said 'fibers together and for imparting a tone effect to said fabric consisting of threads wound spirally about said fibers in opposite directions and colored a different color from ythat of the warp strands of said fabric.

tion and for imparting a tone effect to said fabric, said means comprising wrappings consisting of threads wound spirallyabout said woof strands in opposite directions, and of a smaller diameter than said warp strands and colored `a dierent color from said 'warp strands whereby a tone effect is imparted to said fabric depending upon the color and winding of said wrapping threads.

4. In a grass carpet in combination with a fabric comprising woof strands and warp strands, the woof strands being composed of undyed grass fibers, of color threads for imparting a tone effect to said fabric, said threads being wound spirally about said woof strands in opposite directions to form a double wrapping therefor, and being of a contrasting color to the color of said fibers and differing in color from the warp strands.

5. 'Ihe herein described method of imparting tone effect to grass carpet, having woof strands of undyed grass fibers arranged side by side, and warp strands inter woven with said woof strands, which consists of providing a spiral wrapping for said woof strands of a color different from the color of both said Vwoof strand fibers and said warp strands, said wrapping being wound about said Woof strands in opposite directions and arranged to hold said strands in substantially cylindrical formation.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 10th day of September A. D. 1915.
